What you Need to Know About Cancer Metastasis
Cancer metastasis can be defined as the spread of cancer cells to different parts of the body. Cancers spread when it is in the advanced stage. Cancer tumors can be treated using chemotherapy, operation or radiotherapy. In the past few years, the treatment of cancer metastasis has been problematic. However, due to the advancement in biotechnology, it now easy to control it.
The cancer cells spread when the cancerous cells separate from the affected part and enter the bloodstream or lymphatic vessels. Cancer can spread in three main ways. First, cancer cells can travel through the blood to the nearby parts. Secondly, the cancer cells can travel through the lymphatic system to the nearby lymph nodes. Lastly, the cancer cells can grow directly in the cells that surrounding the tumor. For cancer cells to be able to spread, they must be able to break from the main tumor, be able to move through blood or lymph, be able to grow in the new part and be strong to be able to avoid attack from the immune system of the body.
It is important to note that all types of cancer can metastasize. The rate at which they metastasize depends on various factors. It is important to note that some types of cancer spread faster compared to others. Cancer cells that are more genetically damaged tend to grow faster compared to those with less genetic damage. The rate at which the cancer is growing influences its spread. A fast-growing cancer will spread within a short period of time. Cancers such as colon cancer and chronic lymphatic leukemia are types of cancer that spread very slowly. Lung cancer, inflammatory breast cancer, and acute myeloid cancer are some examples of cancers that spread very fast
Cancer cells from a tumor can spread to almost every part of the body. However, some types of cancer cells tend to spread only to specific parts. Prostate cancer, for example, tends to spread to the bone. Colon cancer is likely to spread the livers and longs. Lung cancers tend to metastasize to the brain and liver. When cancer spreads to other parts of the body, it is still identified by where it originated. For example, if lung cancer spreads to the brain, it will be call brain cancer. A patient will, therefore, receive lung cancer treatment and not brain cancer therapy.
Scientists are now working on new ways of treating metastatic cancer. There are many research firms that have been established such as Cellmig. These companies are discovering new technologies to develop life-changing cancer medicines. These new medicines reduced the number of cancer deaths in the world and thus saving lives. Metastatic cancer is mostly treated using chemotherapy or radiotherapy. Metastatic cancer is treated to shrink the tumor, slow its growth rate, ease the symptoms and help the patient to live for a longer time. To prevent the spread of cancer cells to other parts of the body, it is important to go for screening early. The screening will ensure that the tumor is removed before the cells metastasize.
